Authenticating datasources with LDAP or Kerberos in Amazon AWS

This blog is mainly to showcase one of the community success story with Teiid and Amazon AWS. The need for our community user Ben Kibler was to provide data sources in AWS be participating in Kerberos authentication. Not only participating, he wanted to provide a consistent usage and access pattern, and a light weight integration layer  for these data sources.

He choose Teiid embedded for this purpose, and provided an extension to hook Auth services back into their corporate Active Directory.  With that his applications can participate in kerberos auth with Teiid, and then same token will be delegated to underlying data sources in Amazon AWS. The rest was provided by Teiid.

Read more about it and find the supporting code at https://developer.jboss.org/message/920818#920818

We love to here about your success stories on Teiid. Also, if something is not working for you as you expect, then come engage us in a discussion, together we can solve the issue the OSS way!

Thank You BenK.

Teiid 8.11 Beta1 and 8.10.1 Released

Teiid 8.11 Beta1 is now available from the  downloads  and maven.  Feature highlights since Alpha2 include: TEIID-3434 More caching control over ttls in the result set cache down to the schema/table level. TEIID-3412 MS Access support via the UCanAccess driver. The UCanAccess support is necessary for those running on Java 1.8 as the JDBC ODBC bridge has been removed from the JRE. The waiting continues on EAP 6.4 Alpha1 - it still should be available shortly and should be the platform target for Teiid 8.11 Beta2. Of course, let us know if you find any issues with these early releases.  There's still plenty of time to get fixes into the final release. Teiid 8.10.1 is also available.  It addresses 5 important issues discovered since 8.10 was released: [ TEIID-3409 ] - PostgreSQLExecutionFactory TranslatorProperty annotation in wrong place [ TEIID-3437 ] - Inconsistencies with row count handling [ TEIID-3438 ] - Null value returned from BlobImpl

Tech Tip: Teiid SQL Language MAKEDEP Hint Explained

In this article I will explain what a MAKEDEP hint is, how and when, why it should be used in Teiid. What: MAKEDEP is query hint.  When a query hint is defined in the SQL query it influences the Teiid query planner to optimize the query in a way that is driven by the user. MAKEDEP means "make this as a dependent join". What is a Dependent Join? For example if we have query like: SELECT * FROM X INNER JOIN Y ON X.PK = Y.FK Where the data for X, and Y are coming from two different sources like Oracle and WebService in Teiid, so in relational algebra you can represent above query as Here the result tuples from node X and node Y are being simultaneously fetched by Teiid query engine, then it joins the both the results inside Teiid engine based on the specified X.PK = Y.PK condition and returns the filtered resulted to the user. simple.. Now, what if, if X table has 5 rows and Y table has 100K rows? In order to do the JOIN naively Teiid need sto read all the 5
